CARBURETION MEANS.

' Application filed September 9, '1925. Serial No. 55,225,

My invention relates generally to devices for cleaning and for moistening air andparticularly to such devices associated withor related to carbureting devices.

The main objects ofmy invention are first, a simple and eliicie-nt means for cleaning as well as moisteningl air to kbe used for carburetion purposes; second, to prevent water from mixing-bodily with the oarbureted` air in the carbureting device; third, to prevent condensation of the moisture inthe air between the air moistening means and the outlet end of the carbureting means; fourth, to clean and to moisten the air before it reaches the water in the carbureting device; fifth, vto provide means on suchy an apparatus vfor Vshowing the state of the interior of the apparatus; sixth, to provide adjusting means for the water level in the apparatus as,` well as forthe suctionchambers thereof'.

It is well known, for instance, that, in many instances an internal combustion engine using gasoline and associated with an automobile having a carburetor for thel gasoline, works much better lin cool'and moist air than in hot and dry air. Since free air is taken into the carburetor, ita'p'pearsthat such an engine could be Operated better in all kinds of free air conditions whenl some. means is provided thereon orconnecte'd therewith to supply the carburetor with moist air. My

invention aims to supply such carburetors, or other similar devices, with air having the requisite amount ofvmoisture incorporated therein. Y

My invention is illustrated in the accompanying drawing in which Fig. 1 is aysectional perspective View of an apparatus embodying the. features of my invention showing the air cleaning and moistening device associated with a carburetor and with a water receptacle and also showing a waterrgageand a float-'and a'valve means toregulate'the water level and adjusting means forthe'chanibers associated with the cleaning-and moistening device. Fig. 2 is a section taken' on a horizontal planeindicated by the yline 2-2 in Fig. 1 and shows more clearlythemounting of the spacers and the relationsA of thel hood and the receptacle and the spacers.

VSimilar reference characters refer to simi-v lar parts throughout the views. y

. Applicant is aware that modifications may be made, within the scope of the appendedk claims, in the `form and inthe arrangement- '.of' elementsfand thatfa less number'of elements may be yused withcorresponding reduction in convenience of manufacture or Operaf tion. f v Y )referring now particularly to thel draw- Thecleanihg and moistening device of the apparatus shown has the water receptacle A provided with the free air intake 10 which is open at each end." The cap B is securedto the upper end of the receptacle A.

The hood C is disposed within the receptacle A Vand has-'the flange llextending all around the same and spaced from rthe inside of the wall 12 to provide the passage-way 13.

The spacers yIl, three in the 'present instance, are seated inv vsockets providedk in the flange 11 andA contactgthe wallj12'to keepthe hood C in central position 'i and thereby retain the space or passage-way 13 ofeq'ual widthall around; this is an'advantage but not an ab solute necessity. n

The lower end ofthe hood C is provided with the inclined radial flange 14 to'forin an abutment wall for the water as will appear presently and is also provided with the tubular portion 15 extendingbelow the .flange 14 for the purpose appearingpresently.

The upper end of the cap B is provided v with the hollow ball 16 in vcommunication. with the interior of the cap B through the neck 17. The tube 18 connectsv the hollow of the ball'l'with the rair intake end of the carbureting element'or device D. The tube 18 is here shownin a long'` arcuate sweep to prevent condensation of the moisture in the air as will appear presently.

The rod 19 has the lower end thereof` secured to the upper end of the hood Cl and passes through theneclcl and through the ball 16 and yhas the upper end-thereof' threaded for the adjustingnuts 20. By means of the nuts 20, the hood C can be lowered -to decrease the volumey of the chamber 21 and' increase the volume of the vchamber 22, or the hood can be raised to increase the `rvolume of the chamber 21 rand decrease the volume of the chamber 22- for purposes appearing presently. I

The water gageE is attached to the side of the cleaning `and moisteningfdevice to show the stage of the-water level in the receptacle A. n Y The fioat receptacle F has the bottom thereof associated with the receptacle A. The

los

the valve float 23 is disposed within the receptacle F and has :the rod 241. extending upward and through the cap 25 and is threaded at the upper end ior the adjusting nuts'26A one ot which has the pins 27 projecting from two sides thereof to engage the forked end 28 ot the lever 29 tor the purpose appearing presently.

The water supply tank G, either a tank or a radiator or vother device,'has the outlet 3U for one end of the pipe 31. and the fioat receptacle F has the inlet 32 for the other end of the pipe 3l. c

Intermediate the ends ot' the pipe 31 is 33 having the stem 34C projecting upward and operatively connected to the outerend oit the lever 29 which lever is 'tulcruined at 85 on the standard 36.

The relief valve 87 is provided on the cap B to relieve either excessive vacuum or excessive pressure in the chambers 21 or 22.

As to operation The water gage E shows the stage of the water level in the receptacle A.

By means ot the nuts 26, the flow oi' water from the tanlrGr to the loat receptacle F, through the valve 33, can be adjusted to maintain a certain water level in the recep tacle A.

By means ot the nuts 20, the hood C can be lowered or raised to increase or decrease the volumes of the chambers 21 and 22 and thereby adjust the suction in these chambers to suit the carburetor D or other device an d to suit different degrees ot moisture to be imparted to the air flowing through the receptacle A.

Vhen a suction is created in the chamber 22 through the carburetor D, the air in the chamber 21 has a tendency to equalize or relieve that suction but, in order to reach the chamber 22, the air from the chamber 21 must pass through the water since the tlange 15 projects into the water. Aiter this air has passed through the flange 15 and through the water, it passes upward and, eventually finds its way through the space or passage 13 and into the chamber 22 and out through the pipe 18 and to the carburetor D.

rlhe suction created in the chamber 22 and consequently in the chamber 21, also creates a suction in the tube 10 and thereby causes iree air to enter the chamber 21 through the tube 10.

InV order to prevent the water from passing through the space 13 bodily, l prefer to form the iange 14 as shown so that the water can abut thereon and be thrown back into the receptacle A.

ln order to mitigate the possibility 'oit water being raised bodily, l prefer to malte the inner area. within the flange 15 smaller than the area of the'llange let so that the air passing from the chamber 21 into the water has a more violent contact with the water while it is traveling into and through it than while it is leaving it.

ln general, the air enters the chamber 21 through the tube 10, then travels through the water in the receptacle A, then rises upward through the space 13 and into the chamber 22, and then through the pipe 18 and into the carburetor D.

ln the present arrangement ot the elements shown,,condensation of moisture in the air within the apparatus is taken care of. Whatever moisture is condensed inl the ball 1G travels downward naturally and into the cap B through the neck 17 and whatever moisture is coinlensed in the chambers 21 and 22 naturally finds its way down into the receptacle A. By the time the moistened air `reaches the upper end ot the pipe 18, practically all condensation is complete and there is little lilelihood that any solid water will reach the pipe 18 and whatever condensation takes place in the pipev 18 and enters the carburetor is not of serious disadvantage to the operation of the carburetor.

l/Vhile the air is traveling through the water, all foreign substances, such as sand, dust, ctc., are separated from the air and are retained by the water and eventually find their wayto the bottom oil the receptacle A where they can do no damage and 'from where they can be removed readily. lVhile the air is Vso traveling through the water, it also absorbs a certain amountot' the water and therebybecomes moist air.

This apparatus, then, provides the cleaned as well as the moistened air most advantageous tor the purpose desired and delivers the cleanedair to the carburetor and thereby prevents foreign substance from reaching the carburetor through the air and delivers the moistened air to the carburetor before it is mixed with a volatile hydrocarbon lsubstance and prevents condensed moisture Yfrom reaching the carburetor.
